Instead, set a flag inside the ticker callback and check for that flag inside the loop function.

It is currently not recommended to do blocking IO operations (network, serial, file) from TickerĬallback functions. Library for calling functions repeatedly with a certain period. WiFiServer, WiFiClient, and WiFiUDP behave mostly the same way as with WiFi shield library.įour samples are provided for this library. Sent to the multicast or unicast address. You can use udp.destinationIP() to tell whether the packet received was Udp.beginMulticast(WiFi.localIP(), multicast_ip_addr, port). When listening to multicast packets, replace udp.begin(port) with Udp.beginPacketMulticast(addr, port, WiFi.localIP()). When sending a multicast packet, replace udp.beginPacket(addr, port) with

If you have any problems or suggestions, please post them to the Software Development forum.įor more information, see the API Style Guide for information on making a good Arduino-style API for your library. Check out the library specification for more info on that.įor general questions on the Arduino Library Manager, see the FAQ. If you'd like to make your library available to others in Arduino's Library Manager you will also have to include a library.properties file.

If you'd like to check out the complete library (with keywords and example), you can download it: Morse.zip.

You might want to add some comments that better explain how to use your library. (You can find the sketch using the Sketch > Show Sketch Folder command.) If you restart the Arduino environment (this is the last time, I promise) - you'll see a Library-Morse item inside the File > Sketchbook > Examples menu containing your example. Then, move or copy the directory containing the sketch (let's call it SOS) we wrote above into the examples directory. To do this, create an examples directory inside the Morse directory. It's also nice to provide people with an example sketch that uses your library. You'll have to restart the Arduino environment to get it to recognize the new keywords. Classes should be KEYWORD1 and are colored orange functions should be KEYWORD2 and will be brown. The core of the header file consists of a line for each function in the library, wrapped up in a class along with any variables you need:Įach line has the name of the keyword, followed by a tab (not spaces), followed by the kind of keyword. It might seem a bit strange at first, but it will make more sense once you see the source file that goes with it. We'll call our library "Morse", so our header file will be Morse. The header file has definitions for the library: basically a listing of everything that's inside while the source file has the actual code. You need at least two files for a library: a header file (w/ the extension. Let's start turning the sketch into a library! Finally, there's the call to pinMode ( ) that initializes the pin as an output. Second, there's the pin variable which the functions use to determine which pin to use. First, of course, we have the dot ( ) and dash ( ) functions that do the actual blinking. The sketch has a few different parts that we'll need to bring into our library.

If you run this sketch, it will flash out the code for SOS (a distress call) on pin 13.
